Ho Nieh nominated to the NRC
Nieh
President Trump recently nominated Ho Nieh for the role of commissioner in the Nuclear Regulatory Commission through the remainder of a term that will expire June 30, 2029.
Nieh has been the vice president of regulatory affairs at Southern Nuclear since 2021, though he is currently working as a loaned executive at the Institute of Nuclear Power Operations, where he has been for more than a year.
Nieh’s experience: Nieh started his career at the Knolls Atomic Power Laboratory, where he worked primarily as a nuclear plant engineer and contributed as a civilian instructor in the U.S. Navy’s Nuclear Power Program.
From there, he joined the NRC in 1997 as a project engineer. In more than 19 years of service at the organization, he served in a variety of key leadership roles, including division director of Reactor Projects, division director of Inspection and Regional Support, and director of the Office of Nuclear Reactor Regulation.

Using the earlier formulations for predicting the error in a Monte Carlo game, a few general results about Russian roulette and splitting are obtained. Furthermore, the integral equations for the variance are numerically solved to compare different biasing procedures such as exponential transform and path-length stretching in multigroup transport problems. It is also shown that the results for an infinite medium are close to the results for thick finite slabs. Use of the moments method to solve the infinite medium problem results in considerable saving of computing time.
